Yellow Bird Magnolia: A Guide to Growing and Caring for This Stunning Flowering Tree
Plant Description and Characteristics
The yellow bird magnolia (Magnolia brooklynensis ‘Yellow Bird’) is a hybrid magnolia tree known for its vibrant yellow blooms that appear in the spring. It is a deciduous tree that typically grows to a height of 20 to 40 feet, with a canopy that starts about 5 feet from the ground. The leaves are large and glossy, turning a rich golden yellow in the fall.
Growing Conditions
Yellow bird magnolias prefer acidic soil conditions, with a pH of 5.0 to 6.0. They require well-drained soil and full sun to partial shade. These trees are hardy to USDA hardiness zones 5 to 9, meaning they can tolerate temperatures as low as -20 degrees Fahrenheit.
Planting and Care
When planting a yellow bird magnolia, choose a location that receives ample sunlight. Dig a hole twice the width of the root ball and just as deep. Place the tree in the hole and backfill with soil, tamping down gently to remove any air pockets. Water deeply and regularly, especially during the first growing season.
Fertilize your yellow bird magnolia in the spring after it has finished flowering. Use a balanced fertilizer with a ratio of 10-10-10. Apply the fertilizer according to the manufacturer’s instructions.
Pruning is not necessary for yellow bird magnolias, but it can be done to remove dead or diseased branches or to shape the tree. Prune after the tree has finished flowering.
Propagation
Yellow bird magnolias can be propagated by taking semi-hardwood cuttings in the summer. To do this, take a 6-inch cutting from a healthy branch and remove the lower leaves. Dip the cut end in rooting hormone and plant it in a pot filled with sterile potting mix. Keep the cutting moist and provide bright, indirect light. Roots should develop within 6 to 8 weeks.
Overwintering
Yellow bird magnolias are cold hardy and do not require any special care for overwintering. However, you may want to apply a layer of mulch around the root area to insulate the tree against extreme cold.
Common Diseases
Yellow bird magnolias are susceptible to a few common diseases, including:
- Leaf spot: This fungal disease causes small brown or black spots to appear on the leaves. It is typically not fatal, but it can affect the tree’s appearance.
- Canker: This fungal disease causes sunken, discolored areas to develop on the bark. It can eventually lead to dieback of branches.
- Verticillium wilt: This fungal disease causes the leaves to turn yellow and wilt. It can be fatal to the tree if not treated.
Bloom
Yellow bird magnolias typically bloom in the late spring, with the flowers lasting for about three weeks. The flowers are an opaque yellow color and have an appealing fragrance. They measure about 3.5 inches in width and have a cup-like form with six upright petals.
To encourage more blooms, ensure that your yellow bird magnolia is receiving sufficient sunlight and has acidic soil conditions.
Common Problems
- Spots or dropping leaves: This can be caused by a fungus or bacterial infection. Trim away affected leaves and ensure the tree is receiving adequate sunlight.
- Dying branches: This could be a sign of fungal infection. Remove affected limbs immediately and sterilize your pruning tools.
- Browning leaves: This could be a sign of frost damage, iron deficiency, or other environmental stress. Choose a planting site that is somewhat sheltered from strong winds and perform a soil nutrient test to determine if there is an iron deficiency.
